This older EGO review appears to describe the ST1500 family: a 15-inch cordless string trimmer with a conventional bump-feed head. Check the exact model number before relying on its features. Newer EGO trimmers may have different shafts, heads and loading systems.
The ST1500 family is discontinued
EGO’s legacy 15-inch trimmer page identifies ST1500 and ST1500-S bare tools and the ST1501-S and ST1502 kits as discontinued. The page lists a brushless motor, dual 0.095-inch line and bump feed. It distinguishes the straight-shaft ST1500 from the split-shaft ST1500-S, and lists different battery capacities for the kits.
That distinction matters when comparing listings: a picture of a battery-powered trimmer does not establish that a battery and charger are included. Nor should POWERLOAD or another feature from a newer EGO model be assumed to exist on this one.
Where the design fits
A cordless machine removes fuel mixing and the extension-cord route from routine trimming. For finishing lawn edges and working around obstacles, the relevant questions are whether the working balance suits you and whether the available battery covers your task.
The 15-inch swath is a specification, not a test of performance in every kind of growth. Thick or tangled vegetation can require slower passes and more energy. If your job involves woody stems, choose equipment explicitly approved for that work instead of fitting an unapproved blade to a grass trimmer.
Batteries: verify the complete setup
EGO states compatibility with its POWER+ ARC Lithium batteries on the legacy product page. Still check the exact battery and charger against the tool’s documentation when assembling a used package. Do not interpret a brand name alone as proof that every battery product bearing it is interchangeable.
A larger battery may extend a session but also changes the working weight and balance. For an older pack, remaining capacity matters as well as its label. This review has no controlled runtime test, so it does not promise a fixed number of minutes on either a new or used battery.
Compare prices for complete usable combinations. A bare tool can make sense if you already own approved batteries and a charger. Otherwise, add those costs and check replacement availability before deciding that an older trimmer is the cheaper option.
Head, line and handling checks
Bump feed is different from automatic feed: follow the operating instructions for advancing line. Remove the battery before opening or servicing the head. Check the actual head fitted to a secondhand machine, because previous owners may have replaced it.
EGO’s replacement bump-head listing identifies compatible models. Use that kind of exact match rather than assuming all EGO heads fit all EGO trimmers. Retain the required guard and use the specified line.
Before purchase, inspect the shaft joint where applicable, handle clamp, battery latch and guard. Hold the assembled machine in the intended operating position with its working battery. Specifications alone cannot establish comfort, particularly for an extended edging session.
Weather-resistance terminology is not permission to ignore the owner’s manual or expose a battery tool to unsuitable conditions. Follow the operating, cleaning and storage instructions for the particular unit.
Should you buy a legacy unit?
Consider it if it is complete, its condition is known and the battery system already fits your equipment. Compare it with a supported current model if you need to buy the entire setup, want a different loading system or cannot confirm replacement parts. Discontinued does not automatically mean unusable, but it makes those checks more important.
